Computed Tomography-based Morphological Differences between Histologic Subtypes of Periampullary Ductal Adenocarcinoma.

Objective: To evaluate the computed tomography (CT)-based differences between pancreaticobiliary (PBST) and intestinal (IST) subtypes of periampullary pancreatic ductal adenocarcinomas (PDAC).

Study Design: Analytical study.

Place And Duration Of Study: Faculty of Medicine, Istanbul Medeniyet University, Göztepe Training and Research Hospital, Turkey between 2015 and 2018.

Role of iliac crest tangent in correct numbering of lumbosacral transitional vertebrae.

Background/aim: The iliac crest tangent (ICT) has recently emerged as a reliable landmark to correctly number the lumbosacral transitional vertebrae (LSTV). We retrospectively evaluated the reproducibility and accuracy of the ICT as a landmark in subjects without disc degeneration.

Materials And Methods: Fifty-eight patients with LSTV [19 female, 41 (26–52) years] and 55 controls without LSTV [23 female, 40 (26–55) years] who had undergone spinal computed tomography were included.
